MD-250-HD - A beefed up version of the MD-250

The MD-250-HD was designed to be a performance dynamometer first, with the added benefit of being able to test 2-wheel-drive heavy-duty vehicles such as truck, buses and commercial vehicles. No other dyno in its class offers more value or better in-house motor vehicle testing capabilities than the Mustang MD-250-HD. For starters, the MD-250-HD can boasts a 1,500 horsepower measurement capacity at a top speed of 175 mph and a powerful air-cooled eddy current brake provides the MD-250-HD with 900-hp worth of loading capacity for steady state testing. Do not be fooled by its compact size – the MD-250-HD is a serious dynamometer with serious tuning capabilities.

The MD-250-HD uses a powerful eddy current power absorber, a frictionless, air-cooled braking device, to enable it to apply variable and steady state loading. A complete control and data acquisition system lets you design a wide range of tests or select from a host of pre-configured tests included with the standard system.

The 250-HD’s four roller design makes setting up vehicles a snap – simply drive onto the 250-HD and let the tires settle in between the rollers. The 250-HD can be installed above-ground or below-ground, it’s your choice. The above-ground system utilizes an optional premium platform and ramp system with an above-ground restraint kit. The addition of an axle pull down kit help keep the tires from slipping or trying to “climb out” of the rollers.
